Morning All!
I am going to be dealing with a fairly large building soon incorporating stone & lime walls approx .6m thick. The building has been exposed to the elements and while being renovated is having three new sound proofed beam & block floors added (floors were timber previously). Ground...
Morning Everyone!
I am shortly going to be designing up 2 small circular hot tubs in reinforced concrete.
The hot tubs are located very close to each other resulting in a thin (approx 200mm) walled concrete shell. They are outdoors & buried to ground level. I am concerned with the cracking...
Hi Everyone,
I am going to be designing up an architectural sign (about 6 feet high) on the edge of a coastal cliff shortly. There is a narrow continuous void between the 2 flat wafers of steel on either face. Obviously wind will be an issue.
I was wondering - are there any lattice type /...
Hi Guys,
I'm designing up a steel frame encompassing 1 exterior face of a house extension (from foundation to rafters).
The house is timberframe.
The steel frame has a balcony connected to it.
I have proved the structure is fine for racking. The steel frame is also fine for the moment load...
Morning Everyone,
After some time designing timber frame houses, I have noticed that there does not seem to be many alternative options on the market for lateral bracing to aid wind racking. Ofcourse, the clients would prefer anything less costly than steel racking frames to support the more...
I was just wondering, given the recent incident at the Boston tunnel involving creep failure of epoxy in tensile connections (http://www.ntsb.gov/Publictn/2007/HAR-07-02.htm), are Parallam's certified or tested against creep failure?
Given that Parallam's are more reliant on the long term...
I previously designed up some GLULAM purlins for a long, 45 degree pitch, domestic roof of a timber frame house. Standard C24 solid timber will not work for the loads (fails on bending), is there some form of custom steel knee bracing available to substantially increase the timber capacity...
I'm trying to scour for some way of calculating the shear capacity of 304L stainless steel sheet. BS5950 doesn't cover it, neither does the BSSA (british stainless steel assoc), or the SCI. I have read through any relevant publication I can find on their sites.
I have checked through tables of...

Hi Everyone,
Just found this great forum. I'm looking for a formula that will give the maximum stress and deformation of a thin plate under a triangular pressure load.
Pounder's formulae only seems to cover uniform pressure load, I've looked for a solid week on the internet & in books for a...
